Hi Monique,

We had one fail last year on a hood that was about 20 years old. It was a mess because the access to the counterweights was against a wall so our service provider had a tricky time getting it fixed. There was also a delay in getting the part from LabConco because of the age of the hood. In the end, LabConco sent the wrong part and our technician somehow fished out the counterweights and get everything back together, thankfully. I think a student closed the sash extra hard and the cable came undone (can check my notes tomorrow, at home right now for a snow day :) ).

We don't have a procedure or really inspect the mechanism. Based on this experience, it would be a little time intensive and I'm not sure all mechanisms would be accessible.

I would be interested to hear others experiences as well.

Stay safe, friends on the East Coast!

Hello Everyone,

Has anyone experienced issues with sash mechanisms? I had one fail yesterday from what initially appears to be failure of the belt of the counterweight mechanism. These fume hoods are fairly new and I am wondering how often it is recommended that these mechanisms be inspected. And, does anyone have a written recommended procedure for such inspections that they are willing to share?

Thank you,
